Comment 3 for bug 2047045

Right now, the Ansible output looks like the following with tasks on all hosts running simultaenously (if the number of forks allows for it).
------------------

RUNNING HANDLER [neutron : Restart running neutron-l3-agent container] *********
skipping: [compute02] => (item=compute01)
skipping: [compute03] => (item=compute01)
changed: [compute01] => (item=compute01)
skipping: [compute03] => (item=compute02)
skipping: [compute01] => (item=compute02)
changed: [compute02] => (item=compute02)
skipping: [compute01] => (item=compute03)
skipping: [compute02] => (item=compute03)
changed: [compute03] => (item=compute03)

The proposed fix should hopefully mean it instead looks like this instead, running just one task at a time.
